I tried that .. I was able to reproduce same crash on android emulator .. 
default heap is 24M ( like any android device ).  I tried raising it upto 400Mb 
in steps, but it failed everytime with same error .. but was able to sustain 
longer everytime i increase the heap. Seems that I can not go beyond 400m .. 
the emulator crashed !

In a meeting right now, but you could try Googling for ways to increase the 
heap size on Android?

I did a very quick search and it looked possible

Thanks Mike !
It is failing after few seconds ( about 30-35 secs ) after I get the “Creating 
Package Builder ..” line on the console …I am not getting the next debug 
statement, but getting the exception instead. I am seeing a lot of garbage 
collection calls right after “Creating Package Builder …” line in the console 
before crashing, which tells me that the issue is probably related to 
heap/memory.
Here’s the snippet from my code.
System.out.println (“Creating Package Builder .. ”);
PackageBuilder builder = new PackageBuilder( cfg0 );
builder.addPackageFromDrl(new InputStreamReader(is)); 
// “is” is input stream for drl file
RuleBase ruleBase  = RuleBaseFactory.newRuleBase();
ruleBase.addPackage( builder.getPackage() );
System.out.println (“Package added to rule base.. ”);

Congratulations Abhay!

When does your application crash? e.g. building package, inserting facts, 
firing all rules?


I'm not sure how much help I can be, but your advice might help others.

Unfortunately I'm not able to analyse the Android log :(

Cheers,

I am have now managed to get past all the compiler errors for Drools on android 
.. ( I think ) ☺ .

My app is failing ( crashing ) when run on android device. Looking at the log, 
appears to be a heap memory problem, can anyone see anything suspicious here in 
the android log, that may point to the drools code as suspect ?

No.

You neither tell us the Drools version nor the exact stack trace, let
alone provide all code required to reeproduce the error.

Re: [rules-users] OutOfMemoryError happens when dynamic loading of Rules from Guvnor frequently

2011-06-20 Thread Jason Smith

Try using JMAP to get a heap dump, and then find an analysis tool you like to 
find the memory leak.  It is probably due to a memory leak in MVEL that show 
itself when you do dynamic rules allocation (I don't think it has been fixed 
yet), but I can't be sure unless you find the class that is leaking.

Hi, take a look at JIRA: https://issues.jboss.org/browse/JBRULES-2718.
The fix is in 5.2.0.CR1 which you can get from

Re: [rules-users] Troubles with Oryx designer in Guvnor - jBPM 5.1.CR1

2011-06-20 Thread Tihomir Surdilovic

Really weird error, I cannot reproduce it. Is your Guvnor instance 
running on localhost:8080? Are you using the designer version that ships 
with jbpm-installer or something else?
Another thing to check is if you have any weird JavaScript restrictions 
in your browser. In Guvnor when you create your bpmn2 process, use 
Firebug (in FireFox) in the console tab type in:

frames[3].ORYX.EDITOR.getSerializedJSON()

and post the JSON that gets printed out.

Thanks.

[rules-users] Troubles with Oryx designer in Guvnor - jBPM 5.1.CR1

2011-06-20 Thread Dan Seaver

I'm attempting to use the Oryx designer in Guvnor, however I can't seem to
save / redisplay any diagram. I've tried it with various configurations,
including using the jBPM demo, but always get the same results. After I save
the newly created BPMN diagram, the Oryx designer refreshes to a blank
diagram. The new diagram name is on the list of Guvnor processes (for the
default package), and when I try to open it, I get the same blank diagram.

After starting the jBPM demo (5.1.CR1), I see the h2 database started, jboss
started and the human task service started. The jboss log looks pretty clean
except for an SLF4J error and a mention that the persistence provider caller
for org.jbpm.persistence.jpa does not implement the ejb3 spec correctly.
Also, there is an error regarding the log4j FileAppender.

Then I goto Guvnor with FireFox (or Chrome or IE6) and create the new BPMN
process. I get the following message in the jboss log:

2011-06-20 16:00:05,288 INFO  [STDOUT] (http-localhost%2F127.0.0.1-8080-3)
(null: -1, -1): Premature end of file.

Then I create the process with the designer:

[rules-users] Guvnor guided editor problem - "add more options"

2011-06-20 Thread capeja

Hi all, I'm completely new to Drools and Guvnor and I'm following the "JBoss
Drools Business Rules" book's instructions for getting familiar with Drools. 

When adding action to rule I cannot get the "add more options" feature
working in Guided Editor - "U->" like icon is missing and the "pen" icon
does not work either. For those who have the book, I'm talking about the
example in page 102. The data model is exactly as described in the sample
case. Any idea of what's the problem?

BR,

Pekka

[rules-users] Guvnor 5.2 CR1 under IE8

2011-06-20 Thread Vincent LEGENDRE

Hi all

I was using firefox for Guvnor, every thing was well.
But here, users use IE 8, and under IE8, Guvnor displays some strange list of 
icons in place of some other icons :
   - validate rule dialog : in place of the check (or error icon) : a big image 
containing all icons
   - new rule dialog : category icons are replaced by the same big image
   - history part of a rule : one more time the same big image

Does anyone has the problem ?
Does anyone uses IE :) ?

I suspect something like GWT using a big image as a cache, and some javascript 
to display only a small part of it, and this javascript is not compatible with 
IE. Make sense ? If yes, is there a workaround ?

Re: [rules-users] Trouble getting functions to work in Guvnor

2011-06-20 Thread Wolfgang Laun

Isn't this a simple coding error:
   releaseDate<= ( (ageInDays(current.releaseDate)<100) )
as is compares a Date with a boolean?

I think that the constraint should just be
   eval( ageInDays(current.releaseDate) < 100 )
